In 2002, the Odyssey probe discovered evidence of past ice on Mars. The U.S. Congress authorized the Iraq War resolution. The Anaheim Angels won the World Series. And in a meadow 15 miles north of Flagstaff, scientists began to monitor and move small plots of soil along a mountain gradient… Read more

In a first-of-its-kind warming experiment, researchers at Northern Arizona University found that microbes growth rate decreased over 15 years of warming. The research, published this week in Global Change Biology, showed that under warmer climate conditions, growth decreased among all types of microbes in the community, and suggested that a loss of soil carbon may be responsible… Read more

New study shows a few common bacteria account for majority of carbon use in soil

Posted by Heather Tate on June 8, 2021

Illustration of bacteria in soilJust a few bacterial taxa found in ecosystems across the planet are responsible for more than half of carbon cycling in soils. These new findings, made by researchers at Northern Arizona University and published in Nature Communications this week, suggest that despite the diversity of microbial taxa found in wild soils… Read more

In wild soil, predatory bacteria grow faster than their prey, NAU study shows

Posted by Heather Tate on April 30, 2021

Predators comparison illustrationPredatory bacteria—bacteria that eat other bacteria—grow faster and consume more resources than non-predators in the same soil, according to a new study from Northern Arizona University. These active predators, which use wolfpack-like behavior, enzymes, and cytoskeletal “fangs” to hunt and feast on other bacteria, wield important power in determining where… Read more
